【问题描述】：

我正在处理的应用程序总是给我这个错误

致命异常：主进程：com.map.locationservice，PID：12739 java.lang.IllegalStateException：GoogleApiClient 尚未连接。

下面是我的代码和 androidManifest.xml

知道为什么我总是遇到同样的错误吗？

【参考方案1】：

访问本教程并仔细按照步骤操作。它对我有用。 Create Google Map Application

在此之前，您是否在谷歌开发者控制台中创建了您的项目，并在您的包中添加了您的 SHA1 密钥并检索了您的 API 密钥..？

【讨论】：

是的，我确实有 API 密钥，在调用 startLocationUpdates() 之后发生了 FATAL EXCEPTION

离开您当前的项目，尝试创建一个新项目。如果您使用的是android studio，请按照我给您的视频链接，或者按照这个有完整解释的教程：tutorialspoint.com/android/android_google_maps.htm。如果您使用的是 eclipse，请遵循本教程：examples.javacodegeeks.com/android/core/google-maps/…
